Modern Xiaomi smartphones offer users a wide range of customization options, but access to deep system configuration is often limited by the status of the bootloader. By default, this software protection is activated, which ensures the stability of the operating system and the safety of user data from unauthorized interference. However, enthusiasts and developers often seek full administrator rights for installing customized backups or modified firmware.
The process of deactivating the bootloader protection is a key step in the modification of the device, but it requires careful approach. Wrong actions can lead to blocking the Mi Account account or even turning the smartphone into a brick. In this article, we will discuss in detail all the stages of preparation, the necessary tools and technical nuances that will help you successfully unlock the bootloader without fatal errors.
It is worth noting that this procedure irreversibly changes the security status of your gadget. After disabling Bootloader, the system stops checking the digital signatures of the downloaded code, opening the door to any changes. Before starting any manipulations, make sure that you are aware of the risks and have an up-to-date backup of important files.
What is a bootloader and why turn it off
The bootloader is a special program that runs to the operating system and checks the integrity of its components. In Xiaomi and Redmi smartphones, it is blocked by default, which prevents the launch of unofficial software, a security measure designed to protect the device from malicious code and data theft.
Turning off the bootloader is necessary for those who plan to install custom firmware such as LineageOS or Pixel Experience, and it is also required to obtain Root rights, which give full control of the file system. Without unlocking the bootloader, installing a modified TWRP recavator is impossible.
⚠️ Attention: After unlocking the loader, the data protection mechanism TEE (Trusted Execution Environment may be compromised, making it impossible for banking applications and Google Pay to work without additional manipulation of the security system.
It is important to note that the unlock procedure on Xiaomi devices is officially supported by the manufacturer, but requires compliance with certain rules.You must be prepared for the fact that all data on the internal drive will be irretrievably deleted during the activation of the developer mode.

Unlocking the bootloader is the only legal way to gain full access to Xiaomi’s system for deep modification, but it requires a complete data reset.
Preparation of a smartphone and Mi Account
The first and most important step is to link the device to your account, go to your smartphone settings, select Advanced Settings, and go to Developer Forward. If this is hidden, you need to quickly click on the MIUI version seven times in the About Phone menu.

- 🔐 Use the main Mi Account that will be used to log in to the unlock utility.
- 💾 Make a full backup of contacts and photos as the phone will be reset.
Some users experience an anchor error, which is solved by changing the type of network or trying again after a while, and it is also important to turn off the lock screen or set a simple password to avoid login problems later on.
Installation of drivers and utilities Mi Unlock
To interact with your smartphone in Fastboot mode, you need a Windows computer. You need to download the official Mi Unlock Tool from the developer's website. It's the only software that can officially unblock the bootloader.
Beyond the program itself, it is critical to install the correct ADB and Fastboot drivers, without which the computer will not recognize the device in bootloader mode, usually installed automatically along with platform tools, but in some cases, manual installation through Device Manager is required.
Problems with drivers
Once you have installed all the components, start Mi Unlock and log in to your account. The program will check the status of the device's association. If you have previously linked the phone, the utility will show that the device is associated with this account, and will allow you to move to unlock.
Switching to Fastboot Mode and Connecting
To get your smartphone into Fastboot mode, you need to turn the device off completely. Then press the volume and power buttons simultaneously. Hold them until an image of a rabbit fixing an android appears or the FASTBOOT inscription on the screen.

☑️ Checking before unlocking
In rare cases, antivirus software or firewall can block the connection of the utility to Xiaomi servers. In this situation, it is recommended to temporarily disable the protection or add the program to exceptions. A stable Internet connection on a PC is also a prerequisite.
Unlocking process and waiting timer
Xiaomi has implemented a standby system to prevent impulsive unlocking, and after the first attempt, you can see a message telling you to wait 168 hours (7 days) or 360 hours (15 days) and this timer cannot be circumvented by official methods.
During this period, do not untie your account in your phone settings or reset your device to factory settings, otherwise the timer may reset. Just use your smartphone as normal. When the deadline expires, repeat the procedure for logging into Fastboot mode and launching the utility.
| Parameter | Meaning/Description | Impact on the process |
|---|---|---|
| Account status | Tie-in/Not tied | Unlocking is not possible without a binding. |
| Waiting time | 0 to 360 hours | Depends on the region and account activity |
| Connection mode | Fastboot | The only operating mode is Mi Unlock |
| Internet | Mandatory. | Needed to check the authorization server |
Once the timer has expired, the Unlock button will become active. Press it and confirm the action. The process takes a few seconds, after which the device automatically restarts and performs a data reset.
Possible mistakes and ways to solve them
One of the most common errors is the message "Couldn't verify device." This often happens if you're trying to unlock a device tied to another account, or if too little time has passed since the link.
The error "Current account is different from the account info on the device" indicates desynchronization. Make sure that the phone settings and Mi Unlock program use the same Mi Account. Signing out and re-entering your account on your phone can help.
💡
If the utility is 99% hanging, don't restart your computer. Wait until the process is complete or try another one. USB-port.
There are also bugs associated with the version of the utility itself. If the current version of Mi Unlock does not work, try downloading the previous stable version or, conversely, the beta version from the developer forum. Sometimes Xiaomi servers are overloaded, and it is worth trying to perform the actions at night.
The consequences of unlocking for the user
After successfully unlocking, every time you turn on your phone, for a few seconds, you'll be alerted that the bootloader is unlocked, which is a routine behavior that you can't remove without locking it again, and you can only lock it back on the stock firmware.
Data security is reduced as an attacker with physical access to the device can theoretically try to read data, and some features that depend on system integrity, such as Widevine L1, cease to work, which can reduce the quality of video playback in streaming services to SD.
- 🛡️ Warranty: In some regions, unlocking a bootloader may be a formal reason for refusing warranty service.
- 🔄 Updates: OTA-Updates may be delayed or not arriving at all, requiring manual installation.
- ⚡ Performance: The ability to install custom cores can both speed up and slow down the device.
However, for many users, the opportunities outweigh the potential risks, and you get a device that can be customized to suit your needs by removing the extra features and adding new ones.
